![]() ![]() The first step in development is to launch the Lattice Diamond Design Software and create a new project using the new project wizard. Lattice Diamond Design Software version 2.0.1 with third party software Synplify Pro for Lattice and Active-HDL Lattice Edition.This tutorial is simulation-based and will use software only. This enables 3 to 42 high performance DSP blocks and 55Kbits to 5308Kbits of sysMEM Embedded Block RAM. The Lattice ECP2 is a mid Density (6 to 95K LUT and 90 to 583 IO) device with sysDSP and Flexible Memory Resources. The VHDL modules are provided one must simply create schematic symbols, a top level schematic file, and a Test Bench template for use in Active HDL. The Test Bench will drive stimulus for a combinational carry look-ahead adder which can be found covered in greater detail within another eeWiki article. This tutorial will cover basic Test Bench creation and Active-HDL simulation using Lattice Diamond version 2.0.1 and Active-HDL for the Lattice LFE2-70E FPGA. Viewing Signals in Active-HDL and running a custom Test Bench Introduction.Creating Active-HDL project using custom Test Bench.Generation of Test Bench Template using Diamond’s Design View.Generation of hierarchy using Diamond’s Design View.Instantiation of VHDL modules in a top-level hierarchy.Basic overview of the Lattice Diamond design flow tools.The following topics are covered via the Lattice Diamond ver.2.0.1 Design Software. ![]()
